2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017 In this paper, we design and compare multilevel polar coding (MLPC) and bit-interleaved polar coded modulation (BIPCM) for uplink sparse code multiple access (SCMA) systems that operate over fast and block fading channels. Both successive cancellation (SC) and successive cancellation list (SCL) decoding algorithms are considered.

Constellation Partitioning-Based Scma Codebook Design
, 2023 Abstract A new codebook design is proposed for sparse code multiple access (SCMA) uplink transmissions using constellation partitioning to increase the minimum Euclidean distance. The simulation results show that the proposed codebook design outperforms existing SCMA Codebook in terms of error rate performance. More so, the codebook is suitable
